Why Does My Shin Bone Hurt After Knee Replacement

Lateral Knee Pain After A Total Knee Replacement

Your shin bone is called your tibia. The primary reason we believe this bone hurts is because of the new loading forces being placed on the bone after your surgery.

Before surgery, your knee likely wasnt straight.

Now, after surgery, you may not have a full range of motion yet, but the alignment of the implant is perfectly straight.

This new alignment is placing new stress and strain on the shin bone.

Your body will adapt to these new forces but it will take months and sometimes as long as a year.

Types Of Arthritis That Affect The Knee

Inflammatory arthritis

This broad category includes a wide variety of diagnoses including rheumatoid arthritis, lupus, gout and many others. It is important that patients with these conditions be followed by a qualified rheumatologist as there are a number of exciting new treatments that may decrease the symptoms and perhaps even slow the progression of knee joint damage.

Patients with inflammatory arthritis of the knee usually have joint damage in all three compartments and therefore are not good candidates for partial knee replacement. However, inflammatory arthritis patients who decide to have total knee replacement have an extremely high likelihood of success. These patients often experience total, or near-total, pain relief following a well-performed joint replacement.


Osteoarthritis is also called OA or degenerative joint disease. OA patients represent the large majority of arthritis sufferers. OA may affect multiple joints or it may be localized to the involved knee. Activity limitations due to pain are the hallmarks of this disease.

OA patients who have symptoms limited to one compartment of the knee sometimes are good candidates for minimally-invasive partial knee replacement .

What Happens If I Begin To Experience Knee Pain

Reporting the side effects and symptoms to a physician is the first step for a patient who is having problems with their existing knee implant. The surgeon will then take several different steps to evaluate the pain. The first of these involves discussing how the pain is affecting your life.

Startup pain usually is resolved within a couple of months, but common diagnostic signs of more serious issues include the sudden appearance of pain, difficulty when navigating stairs, and persistent start up pain. Any severe symptoms that limit the patients ability to live their life normally should be reported to a doctor immediately to rule out a more serious diagnosis, such as total failure of the device.

In many cases involving problems with the initial knee implant, the doctor will recommend that the patient go through revision total knee replacement surgery. This involves the doctor taking out some or all of the original parts and replacing them with new ones. Revision surgery is a different procedure than primary total knee replacement. It is more complex and longer procedure and requires extensive advance planning

Knee replacement failure has led to numerous lawsuits being filed against the makers of the devices, including the Arthrex iBalance. If you or someone you know has experienced problems with the Arthrex iBalance Knee, you could have grounds to pursue compensation by filing a lawsuit.

This type of pain can be sudden but is likely a mechanical problem in the knee joint itself. It may be a cartilage tear, ACL/ligament involvement, or loose tissue in the joint.

This pain often stems from and leads to a weakness in the surrounding muscles and imbalances between the leg strength.

TIPS TO AVOID PAIN: focus on strengthening the muscles surrounding the knee joint. This simple 4-part exercise routine can be done by your bedside to jump-start your day with strong, healthy joints!

Establishing A Precise Diagnosis Of Where The Pain Is Coming From Can Be Challenging

Researchers at the Department of Surgery, Southern Illinois University School of Medicine offered this assessment in the medical information publication Instructional Course Lectures to guide doctors trying to help patients with pain after knee replacement.

Establishing a precise diagnosis of where the pain is coming from can be challenging.

According to the research: This is what doctors need to look for in trying to find the source of knee pain after knee replacement:

  • Pain after knee replacement can be classified as intra-articular or extra-articular pain .
  • After intra-articular causes , such as knee instability, aseptic loosening , infection, or osteolysis , has been ruled out, extra-articular sources of pain should be considered.
  • Extra-articular sources of pain can be found after a physical examination of the other joints which may reveal sources of localized knee pain, including diseases of the spine, hip, foot, and ankle.
  • MORE: Additional extra-articular pathologies that have the potential to instigate pain after total knee replacement include cardiovascular problems, tendinitis, bursitis, and iliotibial band friction syndrome.
  • Patients with medical comorbidities, such as metabolic bone disease and psychological illness, may also experience prolonged postoperative pain.

You Have Bad Arthritis

Most people who undergo a knee replacement have either osteoarthritis, the wear-and-tear type of arthritis rheumatoid arthritis, an autoimmune condition that causes joint pain and damage or post-injury arthritis.

Osteoarthritis, rheumatoid arthritis and posttraumatic arthritis affect the knee through different mechanisms, however, these different conditions are similar in that they all result in loss of cartilage, which causes pain and loss of motion, says Nathanael Heckmann, MD, an orthopaedic surgeon at Keck Medicine of USC and an assistant professor of clinical orthopaedic surgery at the Keck School of Medicine of USC. When these symptoms become severe, knee replacement surgery may provide considerable symptom relief by replacing the worn-out surfaces of the knee.

What Causes Pain After Knee Replacement Surgery

Researchers continue to study the many causes of pain after knee replacement surgery. Some are biological and due to conditions present before surgery, while others are due to complications that arise during surgery.

On the biological side, patients suffering from arthritis may experience increased sensitivity because of the ongoing pain that was present before surgery. As well explain below, inflammatory responses and allergy-related problems can also contribute to persistent pain. Another source of pain is referred pain originating from the hip due to a change in alignment.

If you are experiencing ongoing pain after knee replacement surgery, but do not have a medical history of arthritis or the previously mentioned issues, you may be dealing with surgical complications. While your doctor will take steps to prevent problems, its still possible for these to rare issues to occur:

  • Infection
  • Instability
  • Stiffness

Remember to stay open and honest with your doctors. This will help them properly diagnose and treat the problem to get you the pain relief youre looking for.

Sharp Pain After Knee Replacement

A Total Knee Replacement is a surgical procedure whereby the diseased knee joint is replaced with artificial material. The procedure involves cutting away damaged bone or cartilage and replacing it with an artificial joint made of metal alloys, high-grade plastics, and polymers.

If one had knee replacement surgery, chances are very high that they will feel far less pain and can move around much better than before. But they may experience some pain and discomfort which is normal after any other surgery.

Therefore, Physical Therapy is an important part of that recovery. Rehab exercises will also help you walk, climb stairs, and return to other normal activities more quickly. In addition to that one also have to take some precautions for quick recovery.

Ongoing Pain After Knee Replacement: People Need Support And Encouragement To Seek Help

This is a plain English summary of an original research article

People with ongoing pain after knee replacement surgery may experience a sense of futility and believe nothing more can be done. A new study found that that one in five people report ongoing pain after knee replacement surgery, but many do not seek help in dealing with their pain.

The researchers say that improvements in the information given before surgery could help. And it is important that clinicians acknowledge pain at follow-up appointments. This may encourage people to seek help to manage their pain through services such as physiotherapy, surgery, or medication.

In this new study, researchers found that some patients did not want to undergo further treatment because they thought it would not work or be risky, or because they had other health problems to deal with. People were uncertain about what to do about their pain even after consulting their surgeon or GP.

The Ligament Problem Is A Clue That For Some Patients Post Knee Replacement Pain May Be A Problem Of Overdoing It Even While In The Hospital Or Nursing Home

In a study from October 2018, doctors writing in the Journal of Pain Research, looking at why some people had excessive pain after knee replacement surgery asked if this was a problem of overdoing it in the hospital following the surgery? The research measured the results of making patients progressively walk more steps in the hospital or nursing home up to 10 days after the surgery.

These are surgeons and pain management specialists from leading hospitals and universities in Japan talking about patients soon after knee replacement during the surgery recovery.

  • Poor pacing during physical activity is associated with severe pain in postoperative patients
  • Over-activity results in a number of potential injuries to muscle fibers, nerves, bones, and ligaments. These injuries, as well as the repetitive experience of pain, will prolong pain and contribute to neurobiological mechanisms of peripheral and central sensitization.

Knee Replacement Recovery Time Guide

Here we will look at total knee replacement recovery time, including what happens at what stage post-op and how long it typically takes to get back to your usual activity.

If are having or have had only one side of your knee replaced, visit the partial knee replacement recovery time section instead to found out how it will be for you.

Knee replacement recovery time will vary from person to person, and may be affected by:

  • Severity of arthritis
  • Compliance with exercises pre and post-op

Let’s have a look at a typical knee replacement recovery time process.

Expected Range Of Motion

Dos &  donts of recovering after Knee Replacement Surgery.

After knee replacement surgery, it is important to work with a physical therapist to achieve the maximal range of motion. Typically, the range of motion will progress quickly during the first three months and can continue to increase for up to two years following surgery.

Normal motion after knee replacement is defined as the ability to get within 5 degrees of a straight knee and the ability to bend the knee back to 90 degrees. Most knee replacements have movement ranging from 0 degrees to 110 degrees or more.

The optimal motion of the replaced knee can be achieved with a combination of stretches, exercises, and gradual resumption of normal activities. Some surgeons will recommend the use of a machine to bend the knee, called a CPM, .

Initial Swelling And Pain Management After Knee Replacement

Chronic Knee Pain After Knee Replacement Surgery 3 Common Reasons

Most patients have moderate to severe swelling for the first few days after knee surgery. Some patients may also experience this degree of inflammation for several weeks. However, this should ease down within the third to sixth month from the day of the procedure.

You can help your knee recover from the swelling faster with the use of ice therapy. Icing can help reduce inflammation, so long as done immediately after an injury. In the case of knee surgeries, you may have to extend the cold treatment for as long as you have swelling.

Aside from cold therapy, it’s also best to elevate the leg wherein you’ve had knee surgery. This will help prevent too much blood from flowing to the surgical site. The reduced blood flow, in turn, can help reduce swelling.

What Is The Recovery Time After Knee Revision Surgery

It varies, but in most cases, physical therapy will be initiated within 24 hours of the procedure and will continue for up to three months.

Some patients take longer to recover. In some cases, protective weightbearing or limiting the knees range of motion is needed to promote appropriate healing. Therapy will usually continue for up to three months following the surgery. Assistive devices, such as a walker or crutches, will be used early in the convalescence period, and patients will progress to a cane or walking without any assistance as their condition improves.

Possible Benefits Of Total Knee Replacement Surgery

Regardless of whether a traditional total knee replacement or a minimally-invasive partial knee replacement is performed the goals and possible benefits are the same: relief of pain and restoration of function.

The large majority of total knee replacement patients experience substantial or complete relief of pain once they have recovered from the procedure. The large majority walk without a limp and most dont require a cane, even if they used one before the surgery. It is quite likely that you know someone with a knee replacement who walks so well that you dont know he even had surgery!

Frequently the stiffness from arthritis is also relieved by the surgery. Very often the distance one can walk will improve as well because of diminished pain and stiffness. The enjoyment of reasonable recreational activities such as golf, dancing, traveling, and swimming almost always improves following total knee replacement.

Five Reasons Why Knee Replacements Fail

Causes of Pain After Knee Replacement Surgery

Wear and loosening

Properly functioning implants depend on their appropriate fixation to the bone. Fixation is usually achieved by cementing the implant onto the bone. Some surgeons prefer instead to use biologic fixation, meaning no cement placed between the implant and the bone.

Although implants are firmly fixed at the initial knee replacement surgery, they may become loose over time. The cause of loosening may not always be clear but high impact activities, excessive body weight and wear of the polyethylene component may all act as contributing factors. Friction caused by the joint surfaces rubbing against each other wears away the surfaces of the implant, creating tiny particles that accumulate around the joint. In a process called aseptic loosening, the bond of the implant to the bone is destroyed by the body’s attempt to digest these wear particles. During this process, normal, healthy bone is also digested , which can weaken or even fracture the bone.

When the prosthesis becomes loose, the patient may experience pain, change in alignment, or instability.


Revision surgery of the infected knee can take several forms. Depending on the degree of infection and damage, the surgeon will determine one of two basic courses of action:

  • perform a simple washout of the knee while keeping the original prosthetic components in place
  • completely exchange the implants with new ones in a full knee revision operation
  • Instability

    Leg fractures
